Bank of Japan board member Ayano Sato stated on June 30, 2026, that volatile short-term exchange rate movements are undesirable because a weak yen increasingly pressures household incomes by driving up import costs.
Sato noted that Japanese companies are now quicker to pass these higher imported costs onto consumers, meaning currency depreciation could filter into underlying inflation more significantly than a decade ago.

According to reports from investinglive. com and finimize.
com, Sato emphasized that foreign exchange movements ought to be determined in a manner that accurately reflects economic fundamentals, though she declined to comment on specific currency levels.
The central bank faces a complex balancing act as a weaker yen provides a boost to domestic exporters but simultaneously squeezes local households through elevated costs for energy, food, and other essential imports.
Sato explained that it remains difficult to definitively conclude whether recent domestic inflation is primarily cost-driven or demand-driven, complicating the guidance of monetary policy while working with estimates of underlying inflation.
Consequently, the central bank must carefully monitor both the downside risks facing economic growth and the upside risks threatening to push inflation higher.

Independence and Policy Outlook
Sato is the second policymaker appointed to the central bank board under the administration of Japanese Prime Minister Takaichi, following Toichiro Asada, who previously voted against a rate hike in June.
Addressing her relationship with the government, Sato stated she did not receive any specific policy instructions from Takaichi and noted that the legal independence of the Bank of Japan is clearly stipulated by law.
